About These Birds
Great Horned Owl
The great horned owl is the most powerful and widespread owl in the Americas, earning the nickname tiger of the sky. It is one of the earliest nesting birds, often laying eggs in January when snow still covers the ground. Great horned owls are fierce predators, regularly taking prey up to three times their own weight.
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
